Yep then come back here and tell us what happened when you spun them, and we'll tell you if it has an LSD

Just joking...if you spin one wheel and the other spins in the same direction, it's an LSD. An open differential will spin the opposite wheel in the opposite direction.

Taymar

Got it, thanks.

So aside from the LSD being optional, all the other performance-oriented turbo S upgrades were standard on the 89 turbo?

Thank you all again for the wealth of information you're sharing.

If you want to do a quick check when you're looking at a car you can always consult the option codes which are on a sticker under the carpet in the trunk.

MAGK944

That will tell you if the car came with it but not if its got it.

The AOR transmissions were not optional on the 89 Turbos. All came w/ the LSD, cooler and additional hardened components. Whether or not the original trans is still in the car today, is a possible issue.

M758 option was not exclusive to North America. The Turbo S was offered in RoW. It was only called the Turbo SE (special equipment) in the UK. In France it was call the Turbo "Cup". Everywhere else it was the Turbo S.

Virtually no difference in the M44/52 engines compared to the M44/51s, other than the 30 hp output increase which came from high rpm boost increase from the -8 turbo and associated DME/KLR chips. However, do be aware that sometime late in the MY89 production run, the con rods were changed from forged to cast. So late 89Ts will have cast rods, as well as the 90+ RoW engines.

I am under the impression from research that

ALL 1989 US 944 Turbos are 944 Turbo 'S' spec, the S was dropped.

I have (and selected) an 89 Turbo for this benefit.

BobSantos

Yep.

Ben951S: It seems that in 1988, purchasing the S option got you all the performance bells and whistles. I have the impression that buying a Turbo (which now had the beefier engine) in 1989 would allow you to select options a la carte. It's also possible that all imported cars to dealers lots were just maxed out by Porsche as far as performance options, leaving no real choice in the matter for customers.

edit: just looked at some 89 window stickers on-line and it seems that at least the brakes, m030 and improved engine were standard.

Taymar

Thank you all for the help. I have a much better idea about what I'm looking for now.

BobSantos: 89-91 turbo had the same engine as the 88 S.

LSD was still an option in 89, at least that's what Porsche told me, however, by 89, 944's weren't ordered as much as they were bought off the lot, because sales for Porsche as a whole across the board had slowed, most dealers optioned(in this case) the 951 with sporting asperations more so then a "basic" 951.

I have a book with article's from throughout 944 production, a couple test 89 turbo's had no lsd, indicating it was an option.

but lets be honest, who wants a 951 w/o the lsd, so it doesn't matter.

check for m220 on the rear option code plaque in the hatch under the carpet above the spare tire, if it's there, then it should be a LSD, check it, never know if it's been replaced. as mentioned, lift the rear and spin on tire, if the other side spins the same way, then you're good, if not, knock some pricing off(if the seller says it has a lsd).

Taymar

Is there any way to tell from the window sticker? This doesn't mention anything about the transmission oil cooler or LSD:



I'll ask the seller if he can get me a picture of the option plaque.

Oddjob

Porsche AG, or some guy at a dealership parts counter? Can you post or link any of this documentation? I have never come across nor ever heard an 89T that did not come standard w/ an AOR transmission.

Oddjob

My 89T window sticker does include "limited slip differential" as a separate line item on the standard equipment at no extra cost list, its in place of the windshield antenna entry. And does also show 220 on the option sticker.

Copy of the option sticker is also attached inside the cover of the warranty and maintenance book that comes in the owner's manual pouch.

87 944 C

PNA, so P AG. it's in a letter I have from them, I sent for some info on pricing for different options for 944's. the letter shows the 89 951 lsd was an added cost option.

and I guess taymar's window sticker shows this.

Oddjob

Sorry, it was not a paid cost option. The AOR was std equipment.

MB968

Shouldn't there also be a "220" Options code listed on the paper label under the rear hatch carpet.
